Well, the Ruby/Rust syntax would serve us well here too:
$things->forEach(|$v| {
foo($v);
bar($v);
});

I actually like this syntax, but what would it look like for multi-statement closures?
A nested set of curly braces around the body would look pretty messy.
$things->forEach({$v => { foo($v); bar($v); }});

We determined that the arrow between the parameters and the expression
would still be required. Given this limitation I think this syntax is
seviceable:
$someDict
->map({$v => $v * 2})
->filter({$v => $v % 3});
Sometime this week I intend to start another thread that narrows us
down to two choices.
